Description

The KC‐2014 Class 2 Bluetooth Data Module is a highly tuned and completely integrated wireless data transceiver subsystem ready for installation in data devices. The KC‐2014 offers reprogrammable, embedded firmware for serial cable replacement deploying the Bluetooth Serial Port Profile (SPP). Our kcSerial embedded firmware provides an easy to use AT style command interface over Uart. Our kcSerial firmware also provides remote control capability, where our AT commands can be issued remotely from any other Bluetooth device via SPP.

All firmware offered by KC Wirefree can be customized for OEM clients. In many cases a few changes can produce great value by differentiating and improving your product. Firmware can be updated via Uart or optionally, via Usb.

Please see our kcSerial User Guide and kcKeyboard User Guide for more information on specific features and operation.



SPP – Serial Port Profile

The KC Wirefree KC‐2014 data modules come standard with kcSerial which implements (SPP) Serial Port Profile.

The SPP is a very popular widely used profile for transmitting data in place of a serial cable. SPP defines how to set up virtual serial ports and connect two Bluetooth enabled devices. A scenario would be using two devices, such as PCs or laptops, as virtual serial ports and then connecting the two devices via Bluetooth technology.

HID – Human Interface Profile

Our kcKeyboard firmware implements the HID profile defines the protocols, procedures and features to be used by Bluetooth HID including keyboards, mice, game controllers, and media controllers. HID commands are issued via Uart commands, and/or Pio button feature assignments.

HFP – Handsfree Profile

Our kcKeyboard firmware optionally implements the HFP profile and provides wireless control for phones, but without the capabilities of providing an audio link. This can be a convenient addition for a full featured wireless controller device.

IAP – Apple iOS Wireless Profile

Our kcSerial firmware implements the IAP profile that provides a peripheral data link to iOS devices. The IAP profile requires an Apple authentication chip, and finished products require an MFi license from Apple. The IAP profile controls the iOS authentication procedure, and implements the Apple lingo data link requirements.

Other Available Bluetooth Data Profiles

KC‐2014 is capable of supporting additional Bluetooth profiles. Contact KC Wirefree for customization options.

Interface Pins

AIO Interface Pins [1‐2]

AIO 0 and AIO 1 are enabled for analog input by default, providing 8 bit samples at rates up to 50 samples/sec. Analog pins are 1.8V logic for input mode. Voltage reading accuracy is guaranteed to 6 bits resolution.

PIO Interface Pins [3‐10,20‐21,23]

PIO pins are read and write enabled via kcSerial commands. Inputs can be configured for weak pull‐up, weak pull‐down, strong pull‐up, strong pull‐down. Voltage input tolerance and output level is equal to the VDD level.

I2C Interface [7‐9]

The I2C interface pins are hardware assigned to PIO 6 = SDL, PIO 7 = SDA, and PIO 8 = RESET. The I2C interface must be custom programmed per application. It is used for EEPROM, LCD, and Apple Authentication chips (iOS wireless accessories).

VDD Pin [12]

Voltage supply pin accepts voltages between 2.7V and 3.6V. Regulation should have a fast response time < 20µs. It is essential that the power rail recover quickly. We recommend Texas Instruments TLV71333PDBVR. Note, the USB, UART, and PIO pins high outputs will be driven relative to this VDD input voltage level.

SPI Pins [13‐16]

The SPI pins are only available for firmware loading and test tools. SPI test points are highly recommended for emergency diagnostics access.

UART Pins [22,24‐26]

The UART is compatible with the 16450 industry standard. Four signals are provided with the UART interface. The UART pins operate at TTL voltage level and must be translated to higher RS‐232 voltage levels for communicating with PC hosts. A 3.3V buffered signal IC is recommended. It is highly recommended that UART test points are available for external connection to allow firmware reinstallation or updates. If a microcontroller is attached, provide a tri‐state mode to allow external access to the UART lines.

USB Interface [27‐28]

The USB interface is available for custom applications.

Antenna Port [29‐31]

The module already contains a balun‐filter onboard, so the antenna port only requires a standard 2.4 GHz RF transmission line with a 50 ohm load. Design the antenna circuit according to the antenna manufacturer guidelines. Some designs may use a simple chip antenna without additional circuitry. Microstrip design is not critical if the antenna is less than 3mm from the RF pin. A few recommended chip antennas: Johanson 2450AT18B100E, Johanson 2450AT43A100E, or Antenova Rufa A5839. For PCB transmission line design, we recommend the following online calculator: http://www.emclabinfo.com/emc_calc/microstrip.htm



Application Notes

We highly recommend providing a header or test points for the SPI lines. This allows emergency access for diagnostic tools.

We highly recommend providing UART test points to allow firmware reinstallation or updates. If a microcontroller is attached, provide a tri‐state mode with microcontroller to allow external access to the UART lines.

RS232 hardware flow control is disabled in kcSerial v3.0 firmware by default, and can be enabled with AT HwFlowControl E command (this configuration setting is saved in flash memory). It is highly recommended to enable hardware flow control, since data can be lost with poor wireless connections without flow control.

UART interfaces are 3.3V TTL. A voltage level shifter or buffer IC is required when interfacing to higher voltage RS232 ports.

Regulator should have a fast response time < 20µs. It is essential that the power rail recover quickly. We recommend Texas Instruments TLV71333PDBVR.

Power supply to module should have less than 10mVrms noise between 0‐10MHz, and spikes should be minimal.

A voltage level monitor IC connected to RESET is recommended for fluctuating power sources (especially automotive). Flash memory can become corrupted with high or low spiking power sources. We recommend Diodes Inc. APX809‐29SAG‐7 (2.93V).

Unused pins should be unconnected.

The area around the antenna should be free of metal and grounds. Minimum clearance is 5mm, but additional clearance improves RF performance.

Do not use ultra sonic cleaning, which may cause internal interconnect damage to IC’s and crystals.

Driving LEDs directly from PIO pins is not recommended. We recommend using MOSFET gates or a buffer driver.

Firmware Interface

The KC‐2014 offers our powerful kcSerial firmware interface using the UART, which provides an easy to use AT style text command interface. The firmware interface allows persistent storage of configuration parameters such as device name, default baud rate, security PIN, and automatic connection settings. Additionally kcSerial provides operational commands such as discovery, connections, security, read/write commands for I/O pins. These commands are also available in remote command mode, so a kcSerial device will respond to these commands issued locally via UART, or wirelessly via remote command mode.
